Common name

Cape York Cedar; Cedar, Cape York; Buff Mahogany; Mahogany, Buff


Blaze odour strong but difficult to describe, possibly like incense. Wood emitting a fruity odour. Lenticels generally large.


Freshly broken twigs emit an odour like that of Red Cedar (Toona ciliata) timber, onions (Allium cepa) or shallots (Allium ascalonicum). Terminal buds and young shoots densely clothed in short, brown hairs. Elongated pale lenticels usually visible on the twigs. Leaflet blades about 7.5-25 x 2.5-7.5 cm.


Calyx shallowly cup-shaped, lobes variable, usually broad but apiculate at the apex. Outer surface of the corolla glabrous. Petals about 5-8 mm long. Stamens about 6-8. Disk cupular, enclosing the ovary. Ovary sparsely pubescent.


Fruits +/- globular or laterally compressed and lobed, about 25-30 mm long, outer surface glabrous. Sarcotesta white but becoming red in the open fruit. Cotyledons green.


First pair of leaves broadly lanceolate, about 12-18 x 6-9 cm, glabrous, pulvinus obvious at the petiole-leaf blade junction. At the tenth leaf stage: leaves and petioles +/- glabrous when fully developed, leaflet blades shortly stalked and lacking pulvini; small oil dots just visible with a lens. Terminal bud clothed in short, pale +/- prostrate hairs. Freshly broken or crushed roots emit an odour like that of garlic (Allium sativum) or onions. Seed germination time 33 to 91 days.
